Quote of the Day: The world could end

8

Quote of the Day comes from the following preamble to a radio interview the ABC conducted today with someone from the ANU. Actually, the Quote of the Day is just one word, found within the preamble. Can you spot it?

“New modelling from the Australian National University predicts Sydney and Melbourne could experience extreme heatwaves of up to 50 degrees Celsius, by the middle of the century.

“That’s even if the world manages to limit global average warming by two degrees or less, as intended under the Paris Climate Agreement.

“The peer-reviewed research used the latest climate data and modelling techniques including the same ones relied on by the Intergovernmental Panel on Climate Change.”

There’s that magic word:

“Could”.

It’s your XYZ.
